Our invention relates to improvements in heaters for poultry houses and analogous pur oses.

T e primary object of this invention is to provide a heater which may be used in a poultry house having a straw covered floor and other inflammable material, without danger of igniting such material.

Moreparticularly stated, it is our object to provide a heater of any ordinary type with an enclosing casing which will adequately eliminate all danger of overheating any portion of the structure in which the heater may be placed, and in which the danger from sparks, coals, cinders, etc.,- escaping from the heater will be absolutely eliminated without material lossin heating efiiciency, regard being had fora structure which will promote air circulation'throughout the apartment or room in which the heater is located.

In the drawings: v

Figure l is an elevation of a heater embodying our invention with one side wall removed to expose the stove.

Figure 2 is a perspective view with all parts in normal position.

F igure'3 isa detailed view of the upper portion of the stove with parts in section.

Like parts are identified by the same ref erence characters throughout both views.

The stove 10 may be of any ordinary construction, although we preferably employ a cast metal stove having ribs 11 to promote heat radiation, and a feed door 12 in the top wall. The latter may be conical in form, as with a central smoke pipe 13 and a suitable check draft damper 14c affording 13, said communication between a ventilating flue 15 at the'side-of the'stove and the smoke ipe damper being controlled by a t ermostat 16 through the medium of a bell crank 'lever 17 and link rod 18, all located within the ventilating passage 15. The lever 17 may have'one' arm 19 connected by a link 20 with a draft door or damper 21. The thermostat lever 17 and link rod 18 are preferably 10- cated within the ventilating passage 15 in order that the thermostat may be directly responsive to the temperature of the atmosphere surroundingthe base portion of the imetal vertical Walls of the casing.

ficient height heater at a suificientdistance above the floor 29 of the room of any portion of the heater casing with stove and thus control combustion in correspondence with a predetermined temperature desired to be maintained in'the vicinity of the stove and which will generally correspond to the temperature of the room in which the heater is located for reasons which will now be explained.

It will be observed that the heater is located upon the floor 25 of an enclosing casing, the side, front and rear walls of which are spaced at a substantial distance from the stove and provided with air inlet slots 26 at a short distance above the base 25, which slots are partially covered by louvres 27 formed by slitting and upsettingthe sheet The walls of the casing are preferably secured to metal posts, the lower portions 28 of which serve as legs and which support the floor 25 at a substanti 1 distance above the floor 2 9 of the room or building in which the heater is located. The'vertical walls of the casing are secured to the intermediate portions 30 of the postsand the upper portions 31 extend above these walls for a short distance and support a roof 32 which is preferably pyramidal in form as clearly shown in'Figure 2. One of the roof Walls has a section 33 connected to the upper portion 3 1 by suitable hinges 35 .which allow the section 33 tobe swung upwardly against the smoke pipe as indicated.

by dotted lines in Figure 1'. The vertical wall 36-isconnected to one of the posts by hinges 37 and serves as a door, its other margin 38 being connected with the associated post by latches 39, a plurality of latches being preferablyv employed to prevent the door from" becoming accidentally opened; The leg portions 28 of the postsiare of sufto support the flo0r25 of the or building to prevent contact 12 to which access may be had from the top when the lid 33 is raised to the dotted line '95 33 without opening the door 36, I

position in which it is illustrated in Fi ure 1.

The ash pit of the stove is provide with a sliding drawer 37 and when the door 36 is opened, the ashes may be removed by pulling out this drawer by means of its rnob 38, it being thus possible to remove the ashes without da-nger of scattering coals or Cinders into the litter on floor 29.

It will be observed that the louvres 27 curve downwardly over the slots 26. As the heated air within the casing rises, air will therefore be drawn upwardly underneath the louvres through'these slots from the vicinity of the floor 29, the heated air passing outwardly from the casing over the upper margins of the casing walls, such margins being spaced from the roof 32 and said roof overhanging the side wall in such a manner as to deflect the warm air downwardly into the room as it escapes from within the casing. The thermostat is located within the zone of the incoming air currents as they enter the casing from the slots 26., The thermostat will therefore be responsive to the temperature of such air, although the thermostat will preferably be enclosed by the thin walls which form the passage 15. The flue passage is preferably provided withan opening 15 in the wall thereof adjacent its upper end to permit the escape of the air in the passage into the interior of the casing. Ordinarily the check damper 14 will be partially open and a portion of the air will be passing through the passage 15 to the smoke pipe 13. The lower end of the passage 15 is open, the

lower margins of its walls being at a short distance above the floor of the casing, thereby providing substantially continuous ventilation. It will be noted that the walls of the passage 15 extend below the slotted portions of the casing side walls and therefore the air withdrawn from the passage 15 and the smoke pipe is that which tends to settle to the floor 25 and which, by reason of impurities, is heavier than the air which passes upwardly along the sides of the heater and escapes over the upper margins of the side walls from underneath the roof walls.

While we have described the heater 10, the ventilating passage 15 and the thermostatic damper controlling mechanism in considerable detail, we do not wish to be understood asindicating that these features are essential. They are desirable for the purposes stated in the description thereof, but any heater may be substituted without departing from the scope of the invention as set forth 1n the appended claims. The particular heater shown is also preferred for the reason that it isadapted toserve as a brooder stove when not in use as a heater for the poultry house. Brooders will ordinarily be in use at a'period of the yearwhen artificial heat is not required in a poultry house, and these stoves may therefore be made to serve the double purpose of heating the poultry house in winter and brooder houses after the severe winter period is past.

It will be observed that the legs 28 which support the casing, ar of a length substantially equal to or preferably at least one-half the height of the stove contained within the casing. Therefore, the casing is supported at such a height above the floor as to preclude contact of its bottom with the. litter onthe floor. This not only allows the chickens to pass freely underneath the casing to keep the litter distributed, but it also eliminates any possibility that accumulations of litter might develop to such an extent as to bring portions thereof into contact with a heated portion of the casing. It is necessary to guard against carelessness on the part of attendants, who, on some occasions, might allow coals to drop out of the stove into the bottom of the casing, thereby heating a portion to the point where it might ignite litter if the latter were in direct contact with the heated area.

We claim:

1. A poultry house heater having in combination a portable casing provided with a roof spaced therefrom and a closed bottom, legs supporting said casing, a stove mounted on said bottom and having a smoke pipe extending through said roof, a ventilating flue outside of said stove and communicating with said pipe, the lower portion of said flue being spaced from said bottom, and the sides of said casing having openings positioned above the lower end portion of said ventilating flue in order to insure means for continuously ventilating theheater.

2. A poultry house heater having in combination a portable casing having a hinged portion for permitting accessto the interior thereof, and a closed bottom, legs supporting said casing, a stove removably mounted on said bottom, a roof spaced from said casing and of substantially pyramidal form for defleeting the air as it issues from the casing, a ventilating flue on the outside of said stove, the lower portion of said flue being spaced from said bottom, and the sides of said casing havinglouver openings positioned above the lower end portion of said flue in order to insure means for continuously ventilating the heater.

3. A poultry house heater having in combination a portable casing provided with a hinged door on the side thereof and a closed bottom, a roof spaced from said casing to permit the escape of air therefrom, a stove removably moun ed on said bottom and having a smoke pipe extending through said roof, a ventilating flue positioned to one side of said stove and communicating with said smoke pipe, said'ventilating flue having its lower portion spacedfrom the-bottom and an opening in the side wall of the upper portion.
